Drone Mapping
Why Drone Mapping?
Old Technique - New Technology
Drone mapping is really just photogrammetry calculations where we use multiple Images with known specs such as field of view, angle, and distance from object to calculate movement or to calculate the difference in location to create dimensions, this dates back to 1480 when Leonardo da Vinci was experimenting by looking out his window and drawing the adjacent building on the glass. by changing is location inside and marking the difference on the glass he found he could get accurate scale measurements.
With use of our drones, cameras and proprietary software we can produce 2d and 3d maps along with digital elevation models (dem), complete inspection tasks, mining volume calculations, create 3d models, and develop extremely detailed stitched together photos.
9.2 Billion Pixels
460 20p photos stitched together to make one extremely detailed image.
The Color Of Scale
460 photos all with a gps location and using photogrammetry produces a Distance to ground calculation , Can you see more detail?
The Shape Of The Land
Using photogrammetry and the distance to ground calculation a 3d model can be produced that can be used for planning, development, progress reports, and site plan modeling. if the process is repeated a Calculation of the difference can be performed to show what volume of materials that have been added or removed. this is useful for state reporting of mines and pits, or for estimating excavation costs to customer.
See The Difference
With each Digital Elevation Model (dem) a scale is produce and colors are assessed for a range of the elevation, then that is applied to the image creating a much clearer view of the changes in elevation. this helps predict water flows, materials needed to level an area, and reclamation focus spots can be found.
A stitched Orthomosaic is a large megapixel image created by stitching many images together. the resolution can be defined by number of pictures taken and height above ground. these images can be geo-rectified to be location accurate down to a half inch. With that accuracy measurements can be taken and precise locations of field assets can be Logged.
Tell the Whole Story
Working with Wilhelm Land Surveying we can produce near real time imaging that includes survey markings for use in plot surveys, site plans, or to find boundary encroachments during a sale of a property.
